Sure. I can do it if client contacts me.
You dont understand the point. You wont get any "job" here if you dont post your older works or a reference to your old works. People here look for professionals if they need any and just saying that you are very talented wont get any client in the first place.
If you are serious about getting a job in any of the skills that you say you have try it in real life and see how much that works. You could also try freelancing some gigs.
But work reference is important because that is what the client would want to see. They dont want a random newbie from the internet to waste their time.
